Description
Technical field
The utility model relates to a kind of machining fixture, major diameter titanium ring (sealing ring) workpiece machining clamp especially, and this utility model can solve the replacing of major diameter titanium tube plate sealing face, improves the service life of titanium heat exchanger.
Background technology
Titanium and titanium alloy are a kind of emerging rising metal materials, such as wet chlorine very strong corrosion resistance is arranged for some medium, widely use value is arranged in Chemical Manufacture, the most of fixed tube sheet type that adopts of titanium heat exchanger made, wherein the situation of not fitting even peeling off can occur in for a long time use of the sealing surface of titanium composite plate tube sheet.Because titanium material coefficient of friction is large, thermal conductivity factor is little, and has the characteristics such as adhesive, so machined titanium sealing ring (titanium ring) difficulty relatively.
The utility model content
The purpose of this utility model is: propose a kind of major diameter titanium sealing ring workpiece machining clamp, solve the replacing of major diameter titanium tube plate sealing face, the titanium tube sheet is come into operation again, improve the service life of titanium heat exchanger.The technical solution of the utility model is: a kind of major diameter titanium ring workpiece machining clamp, comprise basic supporting plate, fastening bolt, briquetting and cushion block, the basis supporting plate is that diameter is greater than the Circular Plate of titanium ring diameter, even distribution inner ring screw and outer ring screw on each different circle of two diameters of basic supporting plate, every circle inner ring screw and outer ring screw all have 3-12 screw, on the supporting plate of basis the distance of two circles between the screws be 1.5 ~ 2 times to the weld-ring One-sided Widths, cushion block is outside dimension less than the annulus of titanium ring internal diameter or the internal diameter size annulus greater than titanium ring external diameter, thickness is identical with the titanium ring, briquetting is provided with fastening screw, and cushion block and titanium ring are fixed between briquetting and the basic supporting plate by fastening bolt.
Further, the thickness of basic supporting plate of the present utility model is 40mm ~ 80mm, and the thickness of cushion block and briquetting is that the specification of 10mm ~ 20mm. fastening bolt is M10 ~ M20.
Cushion block and titanium ring are pressed on the basic supporting plate, namely machine again behind bolted cushion block and the titanium ring.The replacing that the major diameter titanium ring that utilizes workpiece machining clamp to process can solve major diameter titanium tube plate sealing face.
During Vehicle Processing, the titanium sealing ring places between two round bolts hole.After the boring, deburring, the upper surface car with basic supporting plate is flat again.
The beneficial effects of the utility model are: this utility model can guarantee the Vehicle Processing dimensional discrepancy of titanium weld-ring, and is injury-free during the Vehicle Processing of protection titanium weld-ring.
Description of drawings
Fig. 1 is the utility model machined titanium ring anchor clamps schematic cross-sections,
Fig. 2 is a kind of cross section enlarged diagram of basic supporting plate.
The specific embodiment
Below in conjunction with accompanying drawing and example the utility model is further specified.The step groove 8 of basic supporting plate 1, titanium ring 2, fastening bolt 3, briquetting 4, cushion block 5, inner ring screw 6, outer ring screw 7, titanium ring among the figure.
By accompanying drawing 1 ~ 2 structure occupation mode of the present utility model can be described.
The critical piece structure of titanium ring and anchor clamps is shown in Fig. 1-2, and basic supporting plate as shown in Figure 2.The step groove 8 of basis supporting plate 1, titanium ring (titanium sealing ring) 2, fastening bolt 3, briquetting 4, cushion block 5, inner ring screw 6, outer ring screw 7, titanium ring.
Basic supporting plate 1 is bored two circle bolts hole, and the distance between the two circle bolts hole is 1.5 ~ 2 times weld-ring One-sided Widths, and during Vehicle Processing, the titanium sealing ring places between the two circle bolts hole.
1. after the boring, deburring is put down the upper surface car of basic supporting plate again.
2. titanium sealing ring water cutter blanking is welded and is titanium sealing ring weld-ring, is positioned over the finished upper surface of basic supporting board cart behind the whole circle.Compress titanium sealing ring weld-ring, first car upper surface and inside and outside circle.Be used cushion block, briquetting, fastening bolt, turning and half sealing surface upper surface when pressing inner ring, boring and half sealing surface upper surface when pressing the outer ring, assembly method is as shown in Figure 2.
3. titanium sealing ring weld-ring is pulled down from basic supporting plate, according to the step of the inside/outside diameter size car degree of depth 1mm of basic supporting plate titanium ring, as shown in Figure 2.
14. titanium sealing ring weld-ring is stood up, be pressed on the basic supporting plate half sealing surface of car during another surface pressure inner ring of method Vehicle Processing sealing ring shown in step 3, half sealing surface surface of car again when pressing the outer ring.
15. the Vehicle Processing of titanium sealing ring weld-ring becomes the titanium sealing ring, pulls down from basic supporting plate.
Tighten lower lathe with strap 16. the titanium sealing ring packed in the groove of basic supporting plate, fasten with flitch again, be used for transportation or lifting.The thickness of basis supporting plate is 40mm ~ 80mm. cushion block, and the thickness of briquetting is that the specification of 10mm ~ 20mm. fastening bolt is M10 ~ M20..
The utility model is not limited in the titanium sealing ring, and the sealing ring of other materials is applicable equally.Described major diameter titanium sealing ring workpiece machining clamp, the replacing that solves major diameter titanium tube plate sealing face is not limited in the sealing surface of tube sheet, is equally applicable to other sealing surfaces such as vessel flange.
The utility model is not limited to above-described embodiment, and scope of the present utility model is changed and be no more than to various being equal to.
